This is awesome Kyle. Congrats on the product launch! One won't get the full 3,700 GPH (61 GPM) due to friction loss in the nozzle, hose, etc, so the flow will probably be more like 40-50 GPM - well within the PopAndSon guidelines, so the fine/flour gold capture in a 12 inch wide sluice should be excellent with the right matting and angle. Cheers mate!
Thanks Dan! I did my best to use some slow motion shots from my highbanker and calculated the velocity of the water moving through. I looked for the speed of material that was sort of neutrally buoyant, between the speed of rocks rolling along the bottom and bubbles floating over the top. The volume of water I measured that flows through the 2" suction hose into the sluice should travel through the tube with the cross sectional area I chose at that same velocity. So theoretically the hydraulic energy over the riffles "should" be the same as in the highbanker... The only downside would be only having about 3" of sluice width vs 12. So my guess is that as long as you don't over feed loose material through the sluice, the recovery should be good. That part of the machine is a work in progress though. I'll be able to send out an updated mat profile after some more in depth testing next year. For now, I'm happy with it as it does exchange out and hold heavies, but I don't have the kind of testing behind it yet that I do for my highbanker. The angle of the dredge tube shouldn't matter much. whether it's sloped uphill or downhill wont affect the velocity of the water since it's fully contained within the tube. I think it it floats within 10 degrees of flat you should be good to go! I guess just make a really long dredge tube for now if you're after the powder gold :P
@@CodysGarage I would love to know what you are getting for wattage running that at 18 volts! I saw some numbers high enough to make me worry when I tested that in Australia. Look for something called a "200A watt meter power analyser" on ebay or amazon. They are like $20 and run in line so you can see your power use and predict how long a battery will last. Of course if it work, it works! But I'm sitting at just 185watts and it's sucking very nicely! My impeller may draw more power than the stock as rpm increases and the efficiency gains become more apparent. Test it out and let me know how she goes!
I Like this new set up! I've watched each video on its development, same as your unique highbanker, and impeller. I hope the villagers can make a better living for themselves using it. They seemed very happy with the results of their efforts. Brilliant! Thank you for the videos. Have a safe and comfortable trip back to Canada.
I have not compared the two. I can say they both appear to be built out of plastic of some kind? haha. I've heard a few people say the Goldie Box works well. It seems to be a fluid bed recovery system of some kind, where as mine uses matting like drop riffles for recovery. I bet they both capture gold. My system definitely has not been fully tested yet. I THINK it should catch gold pretty well, but I will be taking a month next year to fully test a wide variety of riffle trays and then update on it's actual FINE gold capabilities then.
Hey no worries, I'm planning on trying to help you test! Are you familiar with gravity dredges? I previously wondered if it was worth it to add a hose or two of free falling water to increase pressure and assist the water flow from the bilge pump. What do you think?
@leylinewalker8729 running extra hose to take advantage of the gravity effect would be neat... but what's sweet about this thing, is that somehow, with just 185 watts, you have all the suction you need. This thing actually rips pretty good! Get a cheap 30ah lifepo4 battery and your getting close to 2 hours straight runtime... Also, definitely report back on your results in the field. I've had difficulty getting testing done due to my location so far.
Just remember in Australia, unfortunatly these are illegal to operate, I love dredging but our laws have destroyed our ways of motorised prospecting with these machines
You Aussie boys better get hold of your country or your going to lose all of your freedoms... Like Canada and England. Fortunately, here Trump will turn our country around
I think the business space you are suggesting is already pretty saturated. Far to much innovation and research has already been done for me to be able to profitably enter that space. I'll stick to the simple things, like finding gold.
Right on! I am definitely looking forward to seeing these used! Good work!
I like the idea of the floating sluice... An idea I was just thinking about today!
Great job all around fam. Keep at it. Gold Squad Out 🤠

I run mine at 18v and the suction is awesome. 💪 Wanting to try it with the bilge impeller upgrade next.

i hope we find at one nice day at "physical product" some nice coffee cups ;-)
If you have enough tail flow in certain situations, you could in theory, use the siphon effect to increase the energy efficiency, I think.
i want one. I will buy later this year or early next year. its fantastic for the price
Have you compared your design against the Goldie box?

Not bad, not bad at all! But could you add a gentle suction nozzle to use in the evening after a hard day's work?
